After I login with my GITHUB login, all I see are two boxes in the middle of the screen and they both say “An error occured.”
Are you able to login with your email or Cloud9 username?
I updated FireFox; but it’s still unhappy.
Even in “private mode” same error. Firefox 43.0.4
yes, I am logged in.
Wow, sadly, one of the resources must come from a cdn that is blocked by the firewall.
Darn, that’s not good at all. See if you can get the admins to unblock that CDN or see if there’s another workaround. I’m afraid I won’t be of much help from here on out
